The movable portion 302b is provided in a region around the hollow hole 302a and opposed to the confluence chamber 301c. The fixing portion 302c is provided on the outer peripheral portion of the resonance piece 302 and is attached to the inlet plate 301.

Continuing to refer to FIG. 9A, FIG. 9B and FIG. 10A, in the embodiment of the present invention, the piezoelectric actuator 303 includes a suspension plate 303a, an outer frame 303b, at least one bracket 303c, and a piezoelectric element 303d. At least one gap 303e and one protrusion 303f. In the embodiment of the present invention, the suspension plate 303a has a square shape, and the suspension plate 303a adopts a square shape. Compared with the design of the circular suspension plate, the structure of the square suspension plate 303a obviously has the advantage of power saving. Due to the capacitive load operating at the resonant frequency, the power consumption increases with the increase of the frequency, and since the resonant frequency of the side-length square suspension plate 303a is significantly lower than that of the circular suspension plate, the relative power consumption is also significantly higher. Low, so the square design of the suspension plate 303a used in this case has the advantage of saving electricity. In the embodiment of the present invention, the outer frame 303b is disposed around the outer side of the suspension plate 303a, and at least one bracket 303c is connected between the suspension plate 303a and the outer frame 303b to provide a supporting force for elastically supporting the suspension plate 303a. In the embodiment of the present invention, the piezoelectric element 303d has a side length which is less than or equal to one side length of the suspension plate 303a. The piezoelectric element 303d is attached to one surface of the suspension plate 303a for applying a voltage to drive the suspension plate 303a to bend and vibrate. At least one gap 303e is formed between the suspension plate 303a, the outer frame 303b and the at least one bracket 303c for gas to pass therethrough. The convex portion 303f is disposed on the opposite surface of the surface of the suspension plate 303a to which the piezoelectric element 303d is attached. In this embodiment, the convex portion 303f may be a body formed by performing an etching process on the suspension plate 303a. A convex structure protruding from the other surface of the surface to which the piezoelectric element 303d is attached is formed.

A chamber space 307 is formed between the suspension plate 303a and the resonance plate 302. The chamber space 307 can be formed by filling a material between the resonant plate 302 and the outer frame 303b of the piezoelectric actuator 303, for example, a conductive adhesive, but not limited thereto. The cavity 302 and the floating plate 303a can be maintained at a certain depth to form the chamber space 307, so that the gas can be guided to flow more rapidly, and the suspension plate 303a and the resonator 302 are kept at an appropriate distance to reduce mutual contact interference. The generation of noise can be reduced. In other embodiments, the thickness of the conductive paste filled between the resonant plate 302 and the outer frame 303b of the piezoelectric actuator 303 can be reduced by the height of the outer frame 303b of the high voltage electric actuator 303. It can avoid the thermal expansion and contraction of the conductive adhesive with the hot pressing temperature and the cooling temperature, which affects the actual spacing of the cavity space 307 after forming, and reduces the indirect influence of the hot pressing temperature and the cooling temperature of the conductive adhesive on the overall structural assembly of the micropump 30. But not limited to this. In addition, the depth of the chamber space 307 affects the transmission effect of the micropump 30, so maintaining a fixed depth of the chamber space 307 is important for the micropump 30 to provide stable transmission efficiency.

As shown in FIG. 10B, in other embodiments, the suspension plate 303a may be outwardly extended by a distance in a press forming manner, and the outward extension distance may be at least one formed between the suspension plate 303a and the outer frame 303b. The bracket 303c is adjusted so that the surface of the convex portion 303f on the suspension plate 303a and the surface of the outer frame 303b form a non-coplanar surface, and a small amount of filling material is applied on the assembly surface of the outer frame 303b, for example, conductive adhesive. The piezoelectric actuator 303 is bonded to the fixing portion 302c of the resonance piece 302 by a heat pressing method, so that the piezoelectric actuator 303 is combined with the resonance piece 302. Thus, the structure of the suspension plate 303a of the piezoelectric actuator 303 is formed by press forming to form the chamber space 307, and the required chamber space 307 is formed by the suspension plate 303a of the piezoelectric actuator 303. The distance is completed, which effectively simplifies the structural design of the adjustment chamber space 307, and also achieves the advantages of simplifying the process and shortening the process time.

It should be noted that the inflow plate 301, the resonant plate 302, the piezoelectric actuator 303, the first insulating sheet 304, the conductive sheet 305, and the second insulating sheet 306 are all transparent to the micro-electromechanical surface micromachining process. The micropump 30 is reduced in size to form a microelectromechanical system micropump.

In the embodiment of the present invention, the operation mode of the micropump 30 is as shown in FIGS. 10C to 10E. Referring to FIG. 10C, the piezoelectric element 303d of the piezoelectric actuator 303 is subjected to a driving voltage to generate a deformation-driven suspension. The plate 303a is displaced away from the inflow plate 301. At this time, the volume of the chamber space 307 is increased, and a negative pressure is formed in the chamber space 307, so that the gas in the confluence chamber 301c is taken into the chamber space 307. The resonator piece 302 is synchronously displaced in the direction away from the inflow plate 301 by the resonance principle, and the volume of the confluence chamber 301c is increased, and the confluence chamber is caused by the gas entering the chamber space 307 in the confluence chamber 301c. The chamber 301c is also in a negative pressure state, and the gas is sucked into the confluence chamber 301c through the inlet hole 301a and the bus bar groove 301b. Referring to FIG. 10D again, the piezoelectric element 303d drives the suspension plate 303a to move toward the flow plate 301 to compress the chamber space 307. Similarly, the resonance plate 302 is moved closer to the inlet plate 301 due to resonance with the suspension plate 303a. The directional displacement, the gas in the synchronous pushing chamber space 307 is transmitted outward through at least one gap 303e to achieve the effect of transporting gas. Finally, referring to FIG. 10E, when the suspension plate 303a returns to the original position, the resonance piece 302 is still displaced away from the inlet plate 301 by inertia, and the resonance piece 302 at this time will compress the chamber space 307 to make the chamber space 307. The gas inside moves in the direction of at least one gap 303e, and raises the volume in the confluence chamber 301c, allowing gas to continuously converge in the confluence chamber 301c through the inlet hole 301a and the bus bar groove 301b. By continuously repeating the operation steps of the micropump 30 shown in FIGS. 10C to 10E described above, the micropump 30 enables the gas to continuously enter the flow path formed by the inlet plate 301 and the resonance plate 302 from the inlet hole 301a. A pressure gradient is generated, which is then transmitted outward by at least one gap 303e to cause the gas to flow at a high speed to achieve the operation of the micropump 30 to transport the gas.

In the embodiment of the present invention, the number of the connecting members 401a is four, which are respectively adjacent to the four corners of the suspension piece 401b, but are not limited thereto. The hollow hole 401c is formed at a center position of the suspension piece 401b. The cavity frame 402 is bonded to the suspension sheet 401b. The actuating body 403 is coupled to the cavity frame 402 and includes a piezoelectric carrier 403a, an adjustment resonator plate 403b, and a piezoelectric plate 403c. The piezoelectric carrier 403a is coupled to the cavity frame 402, the adjustment resonator plate 403b is coupled to the piezoelectric carrier 403a, and the piezoelectric plate 403c is coupled to the adjustment resonator plate 403b. The piezoelectric plate 403c is deformed after being applied with a voltage, and drives the piezoelectric carrier 403a and the adjustment resonator plate 403b to perform reciprocating bending vibration. The insulating frame 404 is coupled to the piezoelectric carrier 403a of the actuator 403, and the conductive frame 405 is bonded to the insulating frame 404. A resonant cavity 406 is formed between the actuating body 403, the cavity frame 402 and the suspension piece 401b.

Refer to Figures 12A through 12C for the operation of the blower box micropump 40. Referring to FIG. 11 and FIG. 12A, the blower box micropump 40 is fixedly disposed through a plurality of connecting members 401a, and the air venting sheet 401 forms an air flow chamber 407 with the bottom of the chamber accommodating the blower box micropump 40. Referring to FIG. 12B again, when a voltage is applied to the piezoelectric plate 403c of the actuator 403, the piezoelectric plate 403c starts to deform due to the piezoelectric effect and simultaneously drives the adjustment resonator plate 403b and the piezoelectric carrier 403a. At this time, the air vent sheet 401 is brought together by the Helmholtz resonance principle, so that the actuating body 403 is moved away from the bottom of the chamber accommodating the blower box micropump 40. Due to the displacement of the actuating body 403, the volume of the airflow chamber 407 is increased, and the internal air pressure thereof forms a negative pressure. Therefore, the gas outside the blower box micropump 40 is connected to the plurality of connecting pieces of the air vent sheet 401 due to the pressure gradient. The gap between the 401a enters the airflow chamber 407 and is concentrated. Finally, referring to FIG. 12C, after the gas continuously enters the airflow chamber 407, the air pressure in the airflow chamber 407 forms a positive pressure. At this time, the actuating body 403 is driven by the voltage to approach the blasting box micropump 40. The direction of the bottom of the chamber moves. The volume of the gas flow chamber 407 is thus compressed, and the gas in the gas flow chamber 407 is pushed, and the gas entering the blower box micropump 40 is pushed and discharged to realize the gas transport flow.

It should be noted that the blower box micropump 40 can also be a microelectromechanical system gas pump produced by a microelectromechanical process. In other words, the air vent sheet 401, the cavity frame 402, the actuating body 403, the insulating frame 404, and the conductive frame 405 can all be made through a surface micromachining technique to reduce the volume of the blower box micropump 40.

It can be seen from the above description that the gas detecting module 22 of the gas monitoring machine 2 of the safety helmet provided in the present invention can monitor the ambient air quality of the user at any time, and can be quickly and stably adopted by the setting of the gas actuator 224. The gas is introduced into the gas detecting module 22, which not only enhances the monitoring efficiency of the gas sensor 223, but also transmits the gas actuator 224 and the gas sensor through the design of the gas first compartment 221b and the gas second compartment 221c of the compartment body 221. The 223 are spaced apart to allow the gas sensor 223 to detect and reduce the heat source effects of the gas actuator 224 when detected, thereby avoiding affecting the detection accuracy of the gas sensor 223. In addition, through the design of the gas first compartment 221b and the gas second compartment 221c of the compartment body 221, the gas sensor 223 can also be prevented from being affected by other components in the apparatus, so that the gas monitoring machine 2 can be detected at any time and anywhere. The purpose is to have fast and accurate monitoring results.

In summary, the helmet provided in this case can be combined with a gas monitoring machine to monitor the ambient air quality of the user at any time by using its gas detection module and particle detection module to achieve the purpose of detecting at any time and anywhere, and Quick and accurate monitoring results, instant access to information and warnings to people in the environment, so that they can prevent or escape immediately, avoiding the health effects and injuries caused by exposure to harmful gases in the environment, and more The use of gas purifiers to achieve the benefits of purifying air quality is highly industrially useful.
